Maybe we aren't saying the same thing. I mean the message you get after rebooting the phone is different... it says something about the phone being rebooted... this one did not. But regardless, Apple has now come out and said the reason it failed was that as the phone was being moved around prior to the keynote, it was actively trying to FaceID the people moving it. Its designed to on allow two fails before pin is required. So those 2 tries could have easily been burned by one person carrying it across the room. Their explanation includes them saying that it didn't fail... it worked as designed. But to me, that is a fail. It shows that the design is bad. It also was much slower when it worked later in the demo, than TouchID. TouchID wasn't broken... so they shouldn't have tried to fix it. The only scenario when TouchID doesn't work really well is when your hands are wet or sweaty. What they should have done is add FaceID, not take away TouchID. Both would have been a great improvement in usability. Instead, they have introduced a new system that will have way more false negatives and result in a much higher need to enter the pin. It will also not work at all in many scenarios that TouchID works extremely well in. Like being in a meeting and wanting to check something kind of under the table so to speak... how are you going to do that with FaceID? There are many scenarios that won't work well with FaceID.
